The figure of 255.3 mg/L CaCO₃ is computed by the laboratory from a 2025 test report for the municipal waterworks, not measured directly. It covers one sample point, with no zone split printed. The waterworks page quotes a similar range, but it is undated, so we did not use it. Limescale build-up in boilers and appliances is likely at this hardness.

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
